clex13.in : Local Interconnect - MOS Current Source

Requires: CLEVER

This example demonstrates the use of CLEVER to analyze non planerised structures such as local interconnects commonly used in current sources and in memory cells. To emphasise the true 3D capability CLEVER, a MOSFET with TiN (titanium nitride) local interconnect between drain and gate is implemented using a trench isolation structure together with realistic layer depositions.

The 3D structure is created using the 3D process simulator VictoryProcess, and is then loaded into Clever for the resiistance extraction.

At the end of the 3D process simulation, a 2D cutline of the structure is plotted to show a representative cross sectional view of the created device. This 2D cross section may be plotted without running the simulation from the stored structure file called "clex13_2D.str" by using the standard tonyplot program. The 3 dimensional structure file can be plotted using tonyplot3d. It should be noted that when using the padding command to create a wider boarder around the masks in conjunction with the cut line statement, a warning in the runtime output will occur informing the user that the cutline defined is larger than the mask area. This is to be expected since the padding command generates a larger simulation volume. This warning can therefore be ignored.

The resistance of the local interconnect is extracted using the Interconnect Resistance Adapt statement in the usual way after defining the conductivity of the TiN material. The value of the extracted resistance is stored in clex14.net.
